WEATHER-STRIP FOR SASHES OR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 366,524. dated July l2, 1887.

Application filed December l5, 1886. Serial No. 22L665. (No model.)

To all whom, it may concern:

.Be it known that I, FRANK P. STONE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in XVeatherStrips for Sashes or Sliding Doors, of which the following is a specification, reference being had to the accompanying drawings.

'The object of my improvements is to provide a weather-strip which is particularly applicable to the sashes of car-windows, but may be applied to sashes generally, or to sliding doors, so as t0 close the openings between the sashes and window-frames on both sides of the sashes-that is to say, on the outside and on the inside. This is particularlyimportant in car-windows, where strong currents of air and much dust are liable to be driven through cracks around window-sashes into cars.

In the accompanying drawings, Figure l is an elevation, partly in section, of a window sash and frame witlr my improvements applied, and Fig. 2 is acrossseetion of the same. Fig. 3 is a sectional detail showing a formal modification.

A indicates an ordinary car-window frame, and B an ordinary glazed sash. rlhe sash is provided with a rubber or other suitable strip or packing, C, upon its opposite edges. This strip, as illustrated, it will be seen, is between the edge of the sash and a wooden strip or slide, D, secured to the edge of the sash over the rubber in any suitable way, as by nails or screws. The slide D is preferably thinner than the sash, and may be apart ofthe sash and projecting from it, and the rubber may be applied in two narrow strips on opposite sides of the slide D; but I prefer to use only one strip of rubber projecting a little outside and inside, and a separate piece, D, as illustrated, because that is the quickest and cheapest Way to embody this part of my improvements; but the slide D may be as thick as the sash, and the rubber C project slightly on each side, as indicated in Fig. 3.

By reference to. Fig. 2 Vit will be seen that the window-frame is made with a recess in section corresponding to the section ofthe sash-that is to say, I provide a wide groove, E, with a narrow groove, F, in its bottom, so as to leave shoulders G. The rubber packing fills the wide groove and bears on either side of it lightly, so as to close the opening effectually on both sides between the sash and its frame. The strip D enters the narrow groove land is provided with springs H, preferably antirattlingsash-springs,su ch as show n in my United States IatentNo. 263,240. These springs .form the principal bearings of the sash upon the frame, and so make it unnecessary for the rubber strip to press very hard upon the frame. Thus the main wear of sliding the sash will be upon the springs, which are enduring, andthe rubber may be so fitted as to cause the minimum friction consistent with tightly packing thejoints. rIhe rubber willof course contract and expand slightly on cit-11er side to accommodate the shrinking and swelling of the sash and frame, so as always to preserve tight joints on the outside and inside of a window, and thus very effectively exclude dust. The tops and bottoms of the sash may be protested in any ordinary Way against the admission of dust.

Vhat I claim to be new, and desire to secure by Letters Patent of the United States, is-

l. The combination, with the sash, of the strip D, the rubber packing interposed between the sash and strip and projecting from both sides thereof, and the anti-sash-rattling springs H, substantially as set forth.

2. The combination, with the sash, of a rubber packing projecting from both sides, a strip, D, and a frame provided with a wide and narrow groove, and shoulders to fit the sash and strip D, substantial y as set forth.

In testimony whereof I have hereunto sub scribed my name.

FRANK P. STONE.
